To all whom it may concern:

Be it known that I, WILLIAM Vmcnx'r SHEL- TON, a subject of the Queen ofGreat Britain,

residing at Constantinople, Turkey,.have invented certain new and usefulImprovements in Alloys, (for which Letters Patenthave been granted inBelgium under date of July 19, 1888, No. 82,610; in Great-Britain underdate, by virtue of international convention, of July 19, 1888,No. 2,722of 1889, and in France under date of December 18, 1888, No. 194,853 andI do hereby declare that the following is a full, clear, andexactdescription of the in vention, which will enable others skilled in theart to which it appertains to make and 'use the same. 1

The object of this inventionis' the production of a species of bronze orbrass of great hardness, toughness, and tensile strength, and capable ofbeing rolled or otherwise worked in either the hot or cold state, thesaid qualig tive proportions of the ingredients used in the manufactureof the product and the in- 2 5 tended applications thereof. The saidproduct is obtained by the combination, as hereinafter more fullyspecified, of copper, iron, manganese, zinc, nickel, silicon, andcarbon.

, I am aware that copper in combination 0 with one or several of theabove-noted elements has been employed in the manufacture of alloys,most of which have, however, been stance, as deficiency in homogeneityand toughness if made hard,'or incapability of being worked hot whenpossessed of ha'rdness and tensile strength. These and other well-knowndefects inherent to most alloys of this class hitherto known areobviated by the present invention, in the execution of which I proceedsubstantially as follows:

In a crucible or furnace of any suitable description are melted copper,nickel, ferromanganese, ferrosilicon, and ferro cyanide 5 of potassium,(yellow prussiate of potash.)

Zinc is then introduced and thoroughly incorporated with the othermaterials. The draft is then lowered and a quantity of carbonate of sodaequal to about two per cent.

SPECIFICATION forming part of Letters liatent No. 423,281; dated March11, 1890.

Application filed November 26,1889. Serial No. 331.692. (No specimens.)Patented in Belgium July 19,1888, N0. 82,610 in England July 19,1888,110. 2,722, and in France December 18, 1888;110. 194,853.

of the weight of the metalin fusion is added thereto, and a few minuteslater the product may be run off into molds of any suitable description.

As above stated, the relative proportions the ingredients have to bevaried according to the qualities required in the alloy. Roughly stated,these proportions may for most practical purposes range within thefollowing 11mits for each hundred poundss weight of copper employed:Zinc, from thirty-four to sixtytwo pounds; ferromanganese, (at abouteighty-four per cent. of v manganese,) four to: 7 six pounds;ferro-silicon, (at about fourteenper cent. of silicon,) one to twopounds; nickel, say from two to four ounces; ferro-cya'nide of 6 5potassium, say'from ten to thirty ounces, and where a specialhardnessand toughness is desired about one per cent. of tin maybe added.V The following table shows a number of]; modifications of the abovetypical proportions, Which may be substituted for the latter thernanufacture of various grades-of my 1m proved alloy, according to thespecial quaL ities desired to predominate therein such as j 7 5hardness, tenacity, ductility, and applicability; to hot or coldworking, as thecase may be.

I nevertheless do notconfine myself to'the proportions therein set forth, which, I repeat,are only given as examples, to be Varied according to circumstances.

-I would observe, in conclusion, that I lay no claim to alloys composedof copper, Zinc, 5- mom, or ferro-manganese and ferro-silicon, which, Iam aware, have long been known and manufactured under diiferent forms;but

What I claim, and desire to secure by Letters Patent, is 1. An alloycomposed of copper, zinc, nickel, iron, manganese, and silicon,substantially as described.

2. An alloy composed of zinc, iron, manganese, silicon, copper, andnickel, the copper I 5 and nickel being in the proportion of one hundredpounds to two to four ounces, respectively, substantially as described.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing 20 witnesses.
